Measurement of wavefront aberration in soft contact lenses by use of a Shack – Hartmann wavefront sensor

Lowerand higher-order wave-front aberrations of soft contact lenses were accurately measured with a Shack–Hartmann wave-front sensor. The soft contact lenses were placed in a wet cell filled with lens solution to prevent surface deformation and desiccation during measurements. Aberration measurements of conventional toric and multifocal soft contact lenses and a customized soft contact lens have proved that this method is reliable. A Shack–Hartmann wave-front sensor can be used to assess optical quality of both conventional and customized soft contact lenses and to assist in enhancing lens quality control. © 2005 Optical Society of America OCIS codes: 170.3890, 170.4460, 330.4460.
